Have you ever traded with someone who charged backed multiple transactions? I'm curious if this ever happens. If no one has successfully managed to do a multi chargeback, then maybe this is a guaranteed protection to be half protected. If chargeback did occur, was it within the same day, or did this happen weeks - month apart? I'm doing some paypal trading again, and being strict on rep(needs payed games, good TF2 activity, no suspicious reports/markings), limit keys, and a few other rep methods. Just trying to see if I can increase the safety just a bit..but then again, maybe it's all just gamble if a good trader might go bad.
